1 claims.

The present invention relates to improvements in cartons. More particularly, it pertains to improvements in cartons made from a single'blank of cut, scored and folded material secured together to provide spaced apart inner and outer side walls in a new and novel manner and having correlated improvements and discoveries whereby the utility of such a carton is considerably enhanced.

Cartons and containers of the collapsible or knock-down type having spaced apart side walls Y have appeared in numerous forms for display purposes. Such cartons are very desirable in emphasizing and'lending decorative effects to their contents when the covers are removed in that a framed appearance is given thereto because of the double wall arrangement which additionally lends great strength to such a construction. However, there are certain disadvantages attendant upon such conventional cartons, particularly in the amount of paper stock which is used, the

complicated set-up features accompanying their erection, particularly in the end panels and the necessary interlocking flaps and other contrivances relied upon to hold such cartons in this condition in more or less permanent form. In assembling such a carto'n 'time is often lost in properly trying to register the interlocking elements during theassembling operation and when this has been completed there is the added possibility that certain portions will become wrinkled or jammed, the carton may not remain in its fixed position and otherwise resulting in an unsightly appearance.

Generally, an object of the present invention, is to provide a carton suitable for display purposes as well as for other purposes wherein spaced apart walls are desirable, which will overcome the foregoing disadvantages, which is economic of manufacture, sturdy yet simple and durable of construction and which can readily and permanently be assembled and secured in its position with ease and facility and without danger that the carton may subsequently become disassembled. v

More specically, it is an object of the present invention to provide a carton suitable for display as well as for. other-purposes for which this type of carton can be used, which readily can be assembled from a cut, scored and folded blank of any suitable, inexpensive material, which has panels that are permanently secured together for ultimate carton formation into spaced apart outer and inner walls in substantial uninterrupted communication with each other, in which the outer walls have integral extensions in overlying relationship with respect to each other and in a manner well suited to provide a reinforced plural-ply bottom for the carton, all of which lie in the same plane, and in which the integral extensions of both the inner and outer walls are secured together and outer walls have extensions which are permanently secured to each other.

Other objects of the inventionv will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises an article possessing the features, properties `and the relation of components which will be exemplified in the article hereinafter described and the scope of the application of which will beindicated in the claims.

For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with-the accompanying drawings, in which:

Fig. 1 is a plan view of a cut, scored and unfolded blank of carton material illustrating one preferred form suitable for assembling into a carton formation in-accordance with the principles of thepresent invention;

Fig. 2 is another plan view depicting the blank of Fig. 1 with a group of aligned inner wall panels inwardly folded over upon a central group of integrally connected outer wall panels;

Fig. 3 is another plan view showing the partially folded blank of Fig. 2 again folded along a transverse median line but at right angles to the former fold so that the portions to each side of said line'overlie each other and being adhesively secured together;

Fig. 4 is a perspective view illustrating the A'folded blank of Fig. 3 in expanded and squared condition;

Fig. 5 is a perspective view showing the squared arrangement of Fig. 4 with bottom portions raised into secured position resulting in the formation of spaced apart side walls; v

Fig. 6 is a longitudinal transverse sectional view taken along the line B-S of Fig. 5 and looking in the direction of the arrows illustrating spaced apart end walls and overlying and overlapping bottom portions; and

Fig. '7 is a cross-sectional view similar to Fig. 6 but taken along the line 1-1 of Fig. 5 and also looking in the direction of the arrows.

Referring now more particularly to Fig. l1 of the drawings there is shown generally at In a preferred type of suitably cut and scored blankl can readily be fashioned into a desired typev of carton. The blank I0 consists of a plurality of aligned ad integral panels some of which are square and some of which are generally rectangular in shape but it is to be understood thatthe particular configuration of these panels need not be as shown inasmuch as they-readily may be altered to providedisptay cartons which are rectangular or squarel in shape having greater or less depth than that illustrated; and it will be further understood that any carton designed to provide the particular shape finally desiredwill of necessity result in panels of compatible configuration. g l

Specifically, the blank I0 has a series of central panels which form outer side walls as indicated at Il, I2, I3 and I4. At the end of the panel I4 isa short extension I5 adapted to receive an adhesive or suitable glue on its opposite surface. Each of the panels II to I4 have along 20 one side score lines I6, I1, I8 and I3 respectively and along their other'sides score lines 20, 2I, 22 and 23. The panel' II has panel extensions 24 and 25 and the panel I3 similarly has panel extensions 26 and 21.A Each of the panels 24 and 2s 26 forming inner side walls is provided preferably with a perforated score'line 23 and 29 respectively. The outer side wall panel I2 also has eXtensions 30 and 3| and similarlyvthe other outer side wall panel has extensions 32 and '33. Each oi' 3c to square the carton of Fis. 3 tofs position ns dethese panels is also equipped preferably with perforate score lines 34 and 35 respectively. Each Aof'the panels 2,4, 39, 26 and 32 are also provided with score lines 33, 39, 43 and 4I respectively. It will also be noted that while the panels I I and I3 have extensions, 25, 26 and 21 respectively, these latter are narrower-'than the panels II and I3, having diagonally cut edges 4,2 between the score lines I6 and 33, I8 and 40, and on the opposite sides of the yscore lines 20 and 22. These panels, therefore, have marginal cut-out portions which extend from the top to the bottom of the resulting carton as will be more fully explained hereinafter. Preferably, the edges of panels 24'V and 26 on the other side of the perforate score lines 28 and 29 are also diagonally clipped for convenience in assembly. The panels 33 and 32 are likewise clippedL at their ends to remove trip angular portions and provide inwardly directed diagonal edges as generally indicated at 43 andit should be noted that this is essential for successfully assemblingbthe carton. It will also be observed that these diagonal edges extend approximately equidistant on opposite sides of the score lines 34 and 35. The portions outwardly extending from the perforated score lines 23, 34, 29 and 35 on their upper faces provide glue flaps v44, 45, 46 and 41 t0 be coated with. any suitable form of adhesive ory glue and this-may be done either mechanically or manuallylsimultaneouslyj with the application of glue on the'funder side of Y e Z -that the spaced apart inner and outer walls appear and when the panels 3| and 33 are suitthe extension panel I5 on panel I4. l l

Referring now more particularly to Fig. 2 it will be seen thatthe blankpf Fig. 1 has been inwardly folded over along the score lines I3, I1, I2 and I9l after the necessary application of Aglue on the glue flaps 4,4, 45, 46 and 41 which are secured to the panels 2,5, 3I, 21 and 33 respectively as indicated. 'I'he panels24, 25, 30 and 3I are then together folded inwardly and over upon panels 26. 21. 32 and 33 and at the same time panel I5 with the` glue on its under side is folded toward the same but in advance thereof in the direction as indicated py the arrow so that the left hand portion of the blank (as observed) -is folded upon- V moved into position. tion, because a rectangular carton is shown which the right hand portion thereof and the panel Il adhesively secured along a marginal portion 4l opposite panel 24.

'I'he resulting'folded and adhesively secured panelcan more readilyi be observed .in Fig. 3 where the arrangement of the various panels in flattened but adheslvely secured position are more,

fully displayed. It is in this knock-down, folded form that the panels can readily beistacked for subsequent application of any suitable glue or adhesive tosecure portions of the bottom. It should be noted at this point that in the absence of glue the carton may readily belsecpred together by any other suitable means such as by stapling, stitching or the like.

After the customer has obtained the carton and is ready to assemble the same it is but necessary picted in Fig. 4. Thereafter the panels" and f21 are ilrst directed upwardly and toward'each other. These panels are the first .which are In the particular illustramight besaid to have side walls and end walls, it is preferable that the extensions 25 and 21 of the outer end walls are first moved into position and, in fact, because of the particular construction of the carton this is essential with a carton having this particular arrangement of cut-out portions. However, whether the carton be square or rectangular it will, inl any instance where the cut-out portions of these bottom panels appear, bethe rst panels which must be moved into positign. These cut-out portions are indicated as beginning at the lower ends of the diagonally cut edges 42 and' extend downwardly to the end of the panel so that marginal areas thereof have 0 been removed. After these panels 25 and 21 pear because of the fact that the extensions 44,-

45,46 and 41 are glued to the panels 2l, 3l, 21 and marginally outwardly of the score lines 20, 2l, 22 and 23 respectively.4 Hence, they move` hingedly'upwardly around these score lines so ably glued or otherwise permanently secured in position the plural-ply bottom is provided. It will be observed that vthe cut-outportions or areas have permitted the squaring and spacing apart of the remaining side walls at the points indicated,A for example. at 49 (see also Fig. 5)

where this edge as well as other edges so cut lle closely adjacent the remaining side walls.

It will be observed from Fig. 6 that the outer walls II and I3 therefore have their integral ex, tensions 25 and 21 opposing each other and their' edges lying short of each other as indicated gcn' tension bottom 25 and erally at 50. It will also be seen that the inner wall panels 24 and 26 have integral extensions in the portions 44 and 46 respectively and that the extension 44 is adhesively secured to the exthat the extension 46 is adhesively secured to the extension bottom 21, all being hinged about their respective score lines. The extension of the outer side walls may more readily be observedby reference to Fig. 7 in which the outer side wall I2 extends integrally around the bottom as indicated and the inner side wall 3B is spaced apart having its integral extension adhesively secured to the bottom panel 3l. Similarly outer side wall panel I4 extends aroundthe bottom of the carton as panel 33 and it-will be seen that this panel overliespanel 3| including the extension 45 and abuts the base of the inner side wall panel 32 where it serves to square the container and maintain it in rigid position, the panel 21 (and panel 25 not shown in this view) having been previously placed in position and the panel 21 shownl here overlying the extension 41 of the inner panel 32. These last named panels also hinge about their respective score lines. It will be seen from this arrangement that because of the overlapping and overlying bottom panels a plural-ply bottom h as been provided which is adhesively secured and reinforced by all the surpluses. It will also be observed that from the Wall I2 the portions 43 permit the areas between the l spaced apart walls to remain in open communication with each other although it will be understood that certain of the panels may be foreyshortened to supply even a greater uninterrupted intercommunication between these spaced apart walls. It will also be appreciated that the extensions of the glue flaps 44 and 46 need not necessarily be diagonally edge cut or tapered but as a matter of convenience in assembly this is desirable. served that either or both of these glue naps, as well as either or both of the glue flaps 45 and 41 may be outwardly directed, i. e. opposite of their illustrated direction so as to lie at the base of the spaced apart walls. It is also within the contemplation"of the invention to provide shorter bottom flaps so that they either abut or have a small marginaloverlap. It is also desirable that one of the integral extensions of the outer wall extend to the opposite inner wall and overlie one of the extensions of the inner wall to abut the base thereof and this is al feature which-is important in that the squaring up and aligning of the container is established and maintained.

No cover has been shown in connection with the present drawings illustrating the carton since any suitable cover may be utilized. Particularly for display purposes the entire assembly or the top may be provided with a material such as Cellophane or other suitable transparent material with which such cartons are conventionally provided.

Because of the strength and rigidity of the carton, the open communication which is established and which can even more fully be increased between the various surrounding spaced apart walls, and because of the -heavily reinforced bottom, it is contemplated that such a carton be used for the packaging of frozen foods, for example, wherein insulation properties by way of surrounding dead air space as well as numerous thicknesses of material is necessary. In this connection it should be observed that the vcover for such a carton can also beVmade-so 'as to provide it with In this connection it should be oba spaced apartwall or, alternatively a cover of a thickness equivalent to the plural-ply bottom of the present container can i It will thus be seen that'theobjects hereinbefore set forth may be in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained-in the above description or shown inthe accompanying drawings shall be interpreted `as in an illustrative and not in a limiting sense.
